Jouy, United states Navy Application october 1s, v1935, serialNo. 45,196 s claims. (ci. 18s- 132) (Granted under the act of March 3,1883, as amended April 30, 1928; 370 Q. G. 757) This invention relatesto wheel chucks, and it -has a particular relation to chucks of acollapsible type for releasably obstructing the movement of the wheelsof an airplane or ther like.

The principal object of the present invention is the provision of arsimpleA and eiiicient wheel chuck of light weight construction which maybe operated from the side and at a safe distance from VAthe airplanepropeller, or propellers, and which may be. collapsed into compact formfor storage rin the airplane.

` With these and other objects in view, as well n .as othery advantageswhich may be incident to the useof ,the` improvements, the inventionconsists of the parts and combinations thereof hereinafter set .forthand claimed, with the understanding that the several necessary elementsconstituting the same may be varied in proportion and arrangementwithout departing from the nature and scope of the invention, as definedin the appended claims.

In order to make the invention more clearly understood, there are shownin the accompanying drawing means for carrying the invention intopractical effect, without limiting the improvements in their usefulapplication to the particular construction, which, for purposes ofexplanation, have been made the subject of illustration.

In the accompanying drawing:

Fig. 1 is a side elevational view of a wheel chuck embodying the presentinvention;

Fig. 2 is a front elevational view of the structure shown in Fig. 1, and

Fig. 3 is an enlarged transverse sectional View taken on line 3-3 ofFig. 2.

. Referring to the drawing, a wheel chuck constructed in accordance withthe present invention is shown as comprising a base Ill which rests uponthe ground and supports a wheel II of an '40 airplane. An abutment inthe form of a plate I2 is connected at its lower edge by hinges I3 tothe forward edge of the base I Il and is formed with an inwardly curvedupper edge I 4, conforming in curvature with that of the tire of thewheel 4,5 II.- 'Ihe adjacent edges of the base I!! and abutment I2 arechamfered, as at I4, so as toI provide a stop to limit swinging movementof the abutment to the right, as viewed in Fig. 1. The abutment I2 isreleasably retained in the posi- 50 tion shown by means of a pair ofcables I5, each having its lower end secured to the base IB and providedat its upper end with a link I6 extending through an opening I'I formedin the abutment I2. The links I6 are releasably retained in B5 positionby pins I8 having a common shank portion I9 formed with an eye 2li, towhich a thong 2l is attached. The pins I8 are prevented from becominglost or misplaced by a short cord 22 attached to theabutment I2.

When it is desired to release the wheels of the* airplane, one of theground crew, standing at one fside of the airplane at a safe distancefrom the propeller, exerts a pull upon the thong 2| of sufpermit thewheel to roll over the same.

When the chuck is not in use the plate I2 may be swung backwardly aroundso as to lie parallel 15 f withthe base Il), thusforming a compactarticle for storage in an airplane. Ii desired, the chuck may beconstructed of sheet metal and the latchl mechanism may be metal straps,provided with suitable apertures. 20

Other modiiications and changes in the proportions an-d arrangement ofthe parts may be made by those skilled in the art without departing fromthe nature and scope of the invention, as

dei-ined in the appended claims. 25 n The invention described herein maybe manufactured and used by or for the Government of the United Statesof America for governmental purposes without the payment of anyroyalties thereon or therefor. 30

What is claimed is:

1. A chuck for an airplane wheel or the like comprising a base forsupporting the wheel, and an abutment mounted on said base for movementbetween an operative position in the path of travel 35 of the wheel, inwhich it obstructs the movement thereof in a forward direction, and aninoperative position without said path in which vsaid wheel is released,said abutment being disposed in contact with the ground and in the sameplane 40 with said base when occupying its inoperative position toprovide a track for said wheel.

2. A chuck for an airplane wheel or the like comprising a base forsupporting the wheel, and an abutment mounted on said base for swinging.movement between an operative position in the path of travel of thewheel, in which it obstructs the movement thereof in a forwarddirection, and an inoperative position without said path in which saidwheel is released, said abutment being disposed in contact with theground and in the same plane with said base when occupying itsinoperative position to provide a track for said wheel.

3. A chuck for an airplane wheel or the like comprising a base forsupporting the wheel, and an abutment mounted on said base for swingingmovement about a horizontal axis between an operative position in thepath of travel in which it obstructsV the movement thereof in a forwarddirection, and an inoperative position Without said path in which saidwheel is released, said abutment being disposed in contact with `theground and in the same plane with said base when occupying itsinoperative position to provide a track for said Wheel.

4. A chuck for an airplane Wheel or the like comprising a base plate forsupporting the whee1, and a plate hinged to the forward edge of saidbase plate for swinging movement between an operative position in thepath of travel of the whee1, in which it obstructs the movement there-Vof in a forward direction, and an inoperative horizontal positionwithout said vpath in which said wheel is released, said abutment beingdisposed in contact with the groundand in the same plane with -saidwbase when occupying its Ainoperative position to provide aitrack forsaid Wheel.

5. A chuck for an airplane wheel ror the 'like comprising a ybaseforsupporting theY wheel, an abutment 'mounted on Asaid base formovement between an operativeposition in the path of travel of Ithewheel and'an'inoperative position without said path in Vwhich saidVWheel -is released, and latch lmeans for releasably vretaining saidabutment in its operative position, said'abutment being disposed incontact with the ground'and in the same plane with said `base whenoccupying its inoperative position toprovide a track for said Wheel.

6. A `chuck for an airplane wheel orthe like comprising a base forsupporting the wheel, an

comprising `a-base for supporting the whee1, an

abutment mounted on said base for movement betweenanf operative positionin the path of travel `ofthe whee1 .and an inoperative position withoutsaid path in which said wheel is released, and latch means, including aiiexble member connecting said abutment with said base, for releasablyretaining ysaid abutment in its operative position, said abutment beingdisposed in contact with 'the ground and in 'the'same plane Iwith'saidbase when occupying its inoperative ipositiondo Apfrovide a'trackfor said wheel. i

Y8. A chuck 'for an .airplane whee1 aortheV like comprising a -base forsupporting'the wheel, an '-1 abutment mounted o'n Vsaid `bas'e'forlmove'ment Y between an operative position"in'thebathbftravel of`une whee1 and aninoperanve position without saidvpath in which saidwhee1 is released, yneans releasably 'connecting'said base Withfsaidabut-'Ai ment, said means including al link `extending throughanaperture inthe latter, and ajpin extending through said link andretractable'there- Lfrom vtotrelease said abutment andthe whee1 remtainedthereby.
